Konova made a huge impact on the scene when they released their very affordable Roller Bearing slider not long ago. Now they are showing off two new slider versions one for heavier cameras and another for extremely light weight cameras (even down to iPhones). Another optional upgrade they will be offering with their future sliders are 'folding legs'. If you're familiar with the basic version, these new folding leg upgrades should make the sliders easier to pack up instead of having to remove them completely off of the slider rail each time you pack. These are both new sliders which are not available yet, and will not be replacing the original current version found below.

Konova is also looking to offer a new three wheel skater dolly similar to a few very high end designs that are already on the market. Using three wheels on a rotating dolly makes it more complicated to line up your subject, but with the use of a Laser pointer, adjustments can be fairly accurate. This new 3-wheeled version (not yet available) will be marketed towards larger and heavier cameras, and will not replace the first version more affordable 4-wheeled version which is found below.
